It is also well suited for applications in power supplies, LED dimming, and audio/video systems. Additionally, the high performance and fast update rate make it suitable for high speed light control applications, such as high speed photography and laser scanning.

Working Principle

The MAX5121BEEE+ converts digital-to-analog through pulse width modulated switching of the reference voltage. The reference voltage is proportionally switched in time by a voltage comparator to reproduce a significantly lower voltage than the reference voltage. The voltage comparison is between a digital code and the 10-bit reference voltage. The output is an analog voltage which is proportional to the digital code. This DAC system provides a highly accurate and fast response time.

Conclusion

The MAX5121BEEE+ is an ideal solution for a variety of data acquisition applications. It is a high-accuracy DAC that provides 10-bit or 8-bit resolution, with a maximum update rate of up to 10MHz. Its fast update rate and high accuracy makes it suitable for applications such as motor control, system feedback, parameter tuning and data acquisition. The MAX5121BEEE+ also provides selectable power saving modes, allowing engineers to choose between normal, low power and highpower operation.
